Research Highlights

Better recognition of manufacturing flaws and structural damage of composites

A UTA researcher is improving reconstruction algorithms and software techniques to produce breakthroughs in computed tomography scanning, which will lead to better recognition of manufacturing flaws and structural damage of composites.

Improved testing of composite materials

A team of UTA researchers is working to develop better modeling methods for affordable, sustainable testing of composite materials, then bring those tools into the certification framework to reduce costs and increase efficiency across the industry.

Studying the causes of traumatic brain injuries

UTA researchers are studying structural damage in neurons and the surrounding perineuronal nets area in the brain and determining where mechanical forces may cause damage by simulating a shock wave-induced cavitation collapse in the PNN.

Developing better bridge inspections

UTA civil engineers are using a non-contact testing system to make faster, easier and more accurate determinations about when and where bridge repairs are needed. The system uses sensors mounted to a moving platform that detects mechanical waves created by an automatic impacting instrument striking the surface of the bridge.

High-resolution nondestructive characterization of composite joints and repairs

Major innovations enabling game-changing non-destructive inspection systems include advanced reconstruction algorithms and software tailored for detection of manufacturing irregularities and structural damage.

Prediction of bonded joint quality and strength from material state measurements

Dielectric bond quality and strength technology is based on measurement of dielectric properties of bonded materials and their correlation with the material state enabling safer application of these heterogeneous bonded systems in aerospace structures. DBQS will impact the repair and certification process of adhesively bonded joints.

Discrete Damage Modeling Methodology Development

UTA researchers are developing advanced computational methods for high-performance computing which incorporate state-of-the-art approaches for modeling multisite evolution and interaction of multiple modes of damage in composite materials and structures under static and fatigue loading in different environmental conditions.

Probabilistic Barely Visible Impact Damage Risk Assessment

Enabling on-the-fly risk assessment of impact damage to composite aerospace structures, using partial or incomplete Non-Destructive Evaluation (NDE) data. The task is achieved by taking probabilistic or partial information from NDE inspection, which is then used to predict the extent of damage, which in turn is used to predict the risk of damage growth or complete failure.

Physics-based, data-driven multiscale modeling of additively manufactured metamaterials.

The process-structure-property-performance relationships of advanced metamaterials and structures are constructed by developing high-fidelity multiscale models and ultra-efficient deep learning models.
